Although I don't know, if this is valid:a) This DVD is only a Bonus DVD coming along with the Planet of the Apes Legacy Collection box set.b) As usual in documentaries, the appearing interviewed guests are not listed in regular credits, but in the middle of the feature - with their first appearance - there are subtitles with their name and their function (I remember, there was an argue about this issue, but I can't find it right now).

Within my profile he is listed as uncredited; if we take this credit as valid, it should be Himself...
